    Answer:

    So we can easily tell that the answer is D. So the + means positive or in the positive side of the graph in the y or x. So that also references direction. The S also stands for South in a compass. C is of course direction down is a direction. That only leaves D which is 2 E or 2e which is a number not a direction. 2e means 2 times euler’s number.

    Answer: D
